Comparative Analysis of Implementation of Solar PV Systems Using the Advanced SPECA Modelling Tool and HOMER Software: Kenyan Scenario

Abstract

Globally, attention has majorly been focused on pollution and exhaustion of fossil fuels allied to the conventional energy sources while the non-conventional energy/renewable energy sources have always been considered clean and environmentally friendly. Of the two, the non-conventional (renewable) is being preferred because it is believed to be more environmentally friendly. Renewable Energy Technologies (RETs) especially Solar Photovoltaics have seen many plants being constructed to either supplement the grid or as alternatives for those far from the grid. Solar Photovoltaics plants occupy large tracts of land which would have been used for other economic activities for revenue generation such as agriculture, forestry or tourism in archaeological sites. The negative impacts slow down the application of Solar PV , but a modelling tool that can easily and quantitively assess the impacts in monetary form would accelerate the Solar PV application. The work presents a developed modelling tool that is able to assess not only the techno-economic impacts but also the environmental impacts in monetary form, for one to be able to determine the viability of a plant in a given region. The results are compared with those of HOMER software.

Assessment of the Use of Renewable Energy Sources for the Charging Infrastructure of Electric Vehicles

“…The correct functioning of the network of charging stations is based on the method of determining their location, depending on a number of factors. In Kibaara et al (2020) and Pashajavid and Golkar (2013) [35,36] studies, it is noted that the places of installation of charging stations with renewable energy sources should take into account the minimum losses from the energy source to the charging station. The calculation of the number of such charging stations and their total capacity is carried out on the basis of the theory of queuing systems and simulation of the features of their functioning [37,38].…”

Barriers to the adoption of the circular economy in the Brazilian sugarcane ethanol sector

“…Renewable energy is a viable alternative to the depletion of fossil fuels (Kapoor et al 2020), and the cycles of materials proposed by the CE will only be effectively closed when the energy used is also renewable (Desing et al 2019). Renewable energy sources are considered clean and environmentally friendly (Kibaara et al 2020). From this perspective, technology and ecology can have a positive in uence on energy companies' strategic decisions (Borowski 2020;Trung, 2020).…”

“…From this perspective, technology and ecology can have a positive in uence on energy companies' strategic decisions (Borowski 2020;Trung, 2020). Using solar systems with photovoltaic technologies (Kibaara et al 2020) and lignocellulose biomass for ethanol and electricity production (Galanopoulos et al 2020) can support the transition to a CE. Perception of innovation through enabling technologies is critical to solutions based on renewable energy systems (Consuelo 2020).…”

Dual Output Voltage Differencing Buffered Amplifier Based Active -C Multiphase Sinusoidal Oscillator

“…Thus, the DO-VDBA has emerged as a promising choice for both VM and CM analog applications in the recent past. Since several structures of MSOs are available, a comparison Table 1 [23][24][25][26][27] and others [28][29][30][31][32] using new advancements in technologies. The pros of the proposed MSO, when compared to the existing structures are that •…”
